Makoto- Wisdom of the Oak.
Mythology: Jupiter is the Roman name for Zeus, who is the Greek king of the gods and also the God of thunder. Zeus controls the weather and is characterized by thunderbolts, which relates to why Makoto's transformation and attacks are based on electricity, lightning, and thunder (you get the point). Zeus also rules over oak trees and eagles, which ties in with Makoto's "oak evolution" attack and her name translation, "wisdom of the oak" (relation to wood).
Zeus is just as crazy about girls as Makoto is about boys (Zeus and Makoto are strikingly similar in that they have strong, self-assured personalities but have a weakness for the opposite sex), and the king of the gods is notorious for having many affairs (like with Hercules' mother...naught, naughty) and making his wife Hera jealous. This also ties in with Makoto and her endless search for love, or boyfriend chasing.
